Almost three years ago, we started ZeroPush because we were frustrated by the complexity involved in sending push notifications to our apps. Our goal was to make developers’ lives easier with simple and powerful tools. Thousands of you agreed, and have used our API to send hundreds of millions of notifications.

It’s akin to an acquihire: ZeroPush cofounders Adam Duke and Stefan Natchev will both work on Fabric, Twitter’s mobile development platform. They’ll be based in Twitter’s Cambridge office.

The tool, which helps developers integrate push notifications into their apps, will shut down in January 2016, and a Twitter spokeswoman said to “stay tuned” to see how ZeroPush is integrated into Fabric. The tool grew from two hundred customers in early 2014 to thousands.
